Logging Drill Run
18. Log Rod 0 (zero)
The first logged point should be recorded when the SST transmitter (in its non-mag housing) is positioned
so that it is ½ in and ½ out of the ground, as shown in the following diagram.
Tooling Position for First Logged Point
Once the tool is in position, then click on the Log button in the upper right of the Steering Tool Data
Upload Control dialog box to log a point. This logged point starts the zero reference of the bore.
If entry is into a pit, measure the difference in depth between the surface of the ground and the center of
the slots in the housing. Enter this depth value as the “Rel. Elev. At Entry” in the Steering Tool Job
Information dialog box.
19. Locate (if possible), Override Data (if necessary),
and Continue to Log
As the tool moves away from the drill, to maintain a straight drill path the heading readings should match
the reference heading
. Based on your steering commands and the tool’s located position (using the
receiver), you can determine if the heading and pitch are correct or if compensation in the LWD log is
required. Be sure to wait a few seconds for all readings to stabilize before pressing the Log button. If the
heading value is incorrect, it can be edited in the Steering Tool Data Upload Control dialog box before
logging the rod to override the measured value. It can also be edited after logging by using the Edit
Steering Tool Data Point dialog box described below. See the
Inputting and Editing Drill Data
section for
more information.
